Application filed MaNf, 1909. Serial No. 496,344.

To aZZ w7wm it may concern:

B'e 1t known that I, CHARLES F. SMITH, a c1t1zen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and'useful Improvements inSafety-Razors," of which the following 1s a specification.

My invention relates to improvements in safety razors, and the objectsof my improvements are simplicity and economy in construction andconvenience and efliciency in use.

In the accompanying drawings :-Fignre 1 is a longitudinal section of myrazor. Fig. 2 is a plan view of the same. Fig. 3 is an end view of thesame; .Fig. 4: is aside elevation of the stropping device to my.razorand a blade. Fig. 5 is an endrview "of the same. Fig. 6- is aperspective view of my guard piece and handle. Fi 7 is a perspectiveview of a blade and hlade back with the blade out about half way fromthe normal position.

.My safety razor is of the type provided with a removable blade and astropping device for 'holdin the blade for convenlence in stropping, alas will be hereinafter described.

A is the guard piece to my razor and comprisesv a piece of sheet metaldoubled back on itself longitudinally to form a tubular back '10, aguard wing 11 on the front side comprismg first a flat portion formingessenh tiall 1; d dl j ti fl e 12 j the bearing points for the frontmember be-' along the edge of the slot in the said tubu lar back 10,then abackwardly projecting upper bearing rib 13, below which the saidguard Wing swells outward and again back and is provided at the lowerend with'a closed combformation l4 comprising'a series of teeth 15,closed at the'outer edge by a bar 16, the said teeth beginning inter--mediate the said swelled portion and curving backward to a point nearthe lower edge to form. an interrupted lower bearing rib 1.7, and thenbending abruptly outward to the said bar 16 at the extreme edge,

The back member of my-guard piece A comprises a downwardly and forwardlypro ecting clamping wing 18, forming essentially a flange extending fromthe back side of the slot in the said tubular back 10, and has at thelower extremity the bearing edge 19 extending longitudinallyintermediate thc sjaid upper bearing rib 13 and the hold the said bladeB within the said in use.

said lower bearing rib 17. The ends and corners 28 of the said tubularback are cut away for facilitating the removal of the blade B and bladeback C to be described, leaving a central portion 20, the resiliency ofwinch is adapted to hold the blade B when in position and in use.

The blade B comprisesaflat piece of steel of rectangular shape, providedalong the center. of the back edge with a short cylindrical guide lug21, preferably cast on in some'suitable manner, of a diameter to fitwithin the said blade back C.

The blade back C comprises a slotted tube of sheet metal having atubular back 22 and provided with short downwardly rojecting flanges 23,along the edges of the s 0t 24:, the

tubular back 22 being adapted to receive 1on gitudinally the saidcastguide lug 21 on the blade B and the said flanges 23 bei adap t-' edto bear against the faces of the lads B and to serve as clamping membersto r' l'dy a 9 back C. Exteriorly the said blade back C is adapted to bereceived longitudinally within the uard piece A, the downwardlyprojecting an cs 23 located between the said downward y projectingflange l2 and the back clampin wing 18,150 that the said blade back Cand the blade B are adapted to be received as a unitwithin the guardiece, the blade being clamped between the root and back members oftheguard piecegi 9.0 rib.17 an "for back 10 and the said closed comb ortion1,4,

in a plane at right an has to t e general alincment of the gua piece andat an angle to the wings suitable for convenience The outer end of thehandle I) is internally threaded as at 24 to receive the threaded outertip 25 of the strapping dc;

vice E. Inwardly from the said threaded tip 25, the said stroppin deviceE comprlses a slotted tube 26 adapte to be received within the saidtubular handle I) and the inperend 27 up to the division notch 30 beingessentially the counterpart-of the saidtubuwhen not in use may blanked'out and rolled up to the tubular said blade back C with the blade Bcon' -ingfof the flanges 23, without appreciably p I ablyspaced and as;

lar back 10 of the guard piece ingly is adapted to receive and hold thevice.

results described are tion'th'at iseoinpact, efficient and reliable.

A and accord I blade B and blade baclp-C as a unit. The outer end 31beyond the said division notch 30 serves conveniently as a handle, andi'na'y have a portion 28' roughened for a friction holding surface. Theslot in the handle end 31 of the stropping device is essentially closed,so. that the edge 32 opposed to the blade B serves as aback stop for thesame when inserted. The stropping device E be conveniently stowed,within the handle I), and secured in by means of the said threaded por-24 and 25 of the handle and stropping The stropping device a strip ofsheet metal,

away place tions device respectively. as described is made of formationand has the outer end closed by the said threaded tip As described. myrazor comprises essentially' a blade holder, guard piece, handle andreceptacle for the stroppingdevice as a unit, and combined with the samea stropping device all self contained and conveniently available foruse. The blades are in diridnally removable and replaceable in the bladeback, and the blade and blade back as a unit are removable andreplaceable in the guardpiece and also in the stropping dc The stroppingmay be effected by means of. the stropping device provided'es scntiallyas is the case with an ordinary razor. The cutting away of the ends andcorners 28 of the tubular back 10, exposes forconvenience in removal,the ends of the tained therein. The closed comb formation 1% of theguard piece A. avoids exposed projecting ends of the teeth. The singleshort guide lug 21 at the back of the blade serves effectively to holdthe blade rigidly in the blade back in combination with the clamptheflexibility of theblade. The

effecting,

obtained by a construe of sheet metal, and comprising handle,

I claim as my invention 1- i 1. In a. safety razor, a flat, thin, sheetmetal blade having a cylindrical guide lug adjacent to its back edge, acombined spring holder and a guard formed of sheet metal and comprisingtwo clamping members suitthe said handle.

a holld'w back by which the said clamping members are united, and asecond spring holder formed of sheet. metal and comprising two clampingmembers suitably spaced, one o the said members having a safety guardformed thereon, and a hollow back that connects the said two members andinto which second holder the said first holder and blade are adapted tobe received and held.

2. In a safety razor, a flat, thin, sheet metal blade having acylindrical guide lug adjacent to its back edge, a holder formed ofsheet metal and comprising two clamping members suitably spaced and ahollow back by which the said clamping members are united, and a secondspring holder formed two clamping members suitably spaced, one of thesaid members having a safety guard formed thereon, and a hollow backthat connects the said two members and into which second holder the saidfirst holder and blade are adapted to be received and held, with ahandle secured to and extending at a right angle to the length of thesaid second spring holder.

3. In a safety razor "having a removable blade, a blade having a backedge, a short guide lug on said back edge, a blade back fitting andadapted to receive said guide lug andprovided with blade clampingmembers, a holder fitting and adapted to receive said blade and bladeback as a'unit, clamping members on said holder adapted to clamp"saidblade and blade back as'a unit, and a guard comprising an extensionof one 0 said clamping members on said blade holder.

e. In combination in a razor having a reinovable blade, a handle, and astropping device, the said handle tubular in formation,

having an open end, otherwise complete and unbroken in its inclosingwalls and provided with an internal screw thread adjacent said end, thesaid stropping device generally tubular information, receivablewithinsaid provided adjacent one end with a screw thread adapted to fitand be received by the said screw thread on said handle, and

at the extreme'end having a tip suitableformanipulation in inserting andwithdrawing said stropping device and for a finish for oiiAnLns F. sMITn. Witnesses:
